Valve's Doug Lombardi on a variety of topics. Along the way Doug mentions their interest in branching out into things like MMOGs and family-friendly games, Steamworks, and Left 4 Dead. Doug admits to another delay for the multiplayer zombie game, which was expected in the summer (story), saying it is now expected for PC and Xbox 360 in November. Doug says he thinks there will be a playable demo (though this may be after the game's release) and that they are kicking around the idea of one of those free Steam weekend deals

Exactly Valve doesn't have suits that push titles out the door that aren't ready. You know when it is released it will be a highly polished game, and you won't have to depend on patches to make it playable.
